Bug fixes

• Remove the load action assertion for memoryless render targets while the render target is not actually memoryless (Intel Macs) e7335c6440688b2c49c9dac51bce126c8bc7bfdf

Enhancements

• MTIContext now automatically chooses to use MTIHeapTexturePool on supported devices. a0fa22797ea3b18fd7d2eb6324a06b19da887791

Deprecation

• MTIVector no longer conforms to NSCoding.

  MTIVector is designed for encoding small vector values for the shader functions. Data serialization should be done using other methods.

• MTIContextOptions no longer conforms to NSCopying.

  MTIContextOptions is designed to be a temporary object. The context does not keep references to the context options. There is no need for the MTIContextOptions to conform to the NSCopying protocol.

Features

• Refactor MTIRoundCornerFilter to support both circular and continuous corner curve.
• Add round corner support for MTILayer.

Enhancements

• Add Hashable conformance to MTIVertex.

Features

• Add MTIRGBColorSpaceConversionFilter for converting between linear sRGB, sRGB and ITU-R 709 color spaces.

Enhancements

• MTIUnpremultiplyAlphaFilter and MTIPremultiplyAlphaFilter no longer inherit from MTIUnaryImageRenderingFilter, this avoids some misuses.
• Internal logic improvements for MTIMultilayerCompositeKernel.
• Color space handling improvements. https://github.com/MetalPetal/MetalPetal#color-spaces

Deprecation

• Remove the MTIUnpremultiplyAlphaWithSRGBToLinearRGBFilter, use MTIRGBColorSpaceConversionFilter instead.

• MTIBlendFilter now accepts images with premultiplied alpha channels.
• You can now assign a mask to MTILayer. #237
• You can now use MTIVideoComposition to process videos. VideoIO is no longer a requirement for video processing. #239 #236

Enhancements

Enhancements

• Improvements for Apple silicon Macs. #229
• Swift API enhancements. e9b192b d1ce01f
• Update the parameter encoding logic of render and compute pipeline kernels. Number types are automatically converted. For example you can now pass int values to float parameters. 1ec9966

Features

• Added tvOS support. #220
• Added kCVPixelFormatType_420YpCbCr10BiPlanarVideo/FullRange support. #218

Bug Fixes
